>If you use how you drive only to predict likelihood of car accident that's ok.

We may say that now, but what if later some algorithm finds there's a hidden correlation between driving performance and race/gender? will it still be an ok metric then? where do we draw the line?

I said that expecting such a correlation to exist.

The line is between inferences of bad behavior -> bad result such as "you drive risky so you must be at risk of an accident" and pure correlation "you drive risky so you must be a man so you must be at increased risk of prostate cancer".

And conclusions should be assumed to be of the latter kind unless shown otherwise.
